Is Libvirt memory ballooning independent from the OpenStack RAM

Overview Part of JNA API describes as following:
1. Description1:
If the native method returns char* and actually allocates memory, a return type
of Pointer should be used to avoid leaking the memory. It is then up to you to
take the necessary steps to free the allocated memory.

1024MB maxMemory and 512MB of currentMemory, I can see just 512MB in guest

Hi ozaki-r,
thank you for answer.
So, there is no posibility that guest can request for more memory (max up to
maxMemory) and libvirt/hypervisor/whatever will automatically increase it? I
have to do it manually?
